Steve -- perhaps I'm a bit off your topic, but -- I have found, strange as it seems, that I shoot much better with any and all bows (necessarily, longbows) that have NO sight window, than I do with centershot bows, whether recurve or hybrid longbows. Just doesn't make sense, yet is true for me. Relating this to your question -- a longbow that's not centershot has NO sight window per se ... yet, has an unlimited vertical sight field. Who knows? Like most everything in life, it gets real personal. I say, shoot whatever YOU shoot best with, and like all matters of faith, don't question it. Dave
